Customized refrigeration systems

Energy efficiency, capital investment, running costs, room size, noise protection, redundancy, local climate – every project has its own specific requirements when it comes to precise air conditioning.

 

Our customers can choose between different configurations and so achieve an ideal balance between capital investment, running costs and energy efficiency. STULZ is the world's only manufacturer to offer such a huge spectrum of configuration options.

A system

Compressor cooling with compressor refrigeration system based on the direct evaporator principle (DX/direct expansion)

The refrigerant circuit of the air conditioning module consists of an evaporator, an expansion valve, a scroll compressor and an external air cooled condenser. Conveyed by a fan, the room air flows through the evaporator, where heat is extracted from it and transferred to the refrigerant. The air conditioning unit and external condenser are connected to one another by means of a closed refrigerant circuit.

 

 

G system

Simple heat dissipation via the water/glycol mixture

Like the A-system, the G-system works according to the direct evaporator principle. With one difference: In the G-system, the heat from the DX circuit is transferred to a water/glycol mixture by a plate-type condenser integrated in the air conditioning unit. The mixture circulates in a closed circuit, and transfers the heat to the outside air via an external heat exchanger.

 

 

CW system
Liquid cooled system

CW units manage without a refrigerant circuit of their own, but require separate chilled water generation. The room air conveyed by the fan flows through the direct cooling unit, which transfers heat to the water/glycol mixture. A chiller removes the heat from this water/glycol mixture. The air conditioning unit and chiller are connected to one another by a closed water/glycol circuit.
